GUI

• Added a wizard to simplify the creation of new workflows
• Extended Network view
  • Workflow components are shown per node (for own node: locally installed and published ones; for remote nodes: published ones)
  • Connections to other nodes are shown
  • Connections to others can be managed (added, edited, deleted, started, stopped)
• Fixed issues regarding copy&paste of workflow components
• Fixed result view of Parametric Study component when it is opened multiple times
• Improved responsiveness of the graphical user interface by reworking long-lasting operations
• General improvements
  • Fix configuration validation in Script component
  • Added additional context menus where applicable
  • Removed tool bar icons for workflow control as they didn't work reliably; may be added again in a future version
  • Removed unnecessary menu entries in the graphical user interface
  • Added button in placeholder page (in workflow execution wizard) to select a file from the file system if the placeholder represents a file system path
  • Added menu entry to switch between workspaces
  • Added menu entry to restart RCE

Workflow Components

• Added generic integration concept to integrate tools as workflow components
  • Tools are integrated using a graphical wizard
  • Newly integrated tools can immediately be made available ("published") to other users
• Fixed constraints handling in Optimizer component for Dakota algorithms
• Made Converger component more robust against inputs that are received after convergence of component
• Restricted input types of Parametric Study component to floating point numbers and integers
• If script in Script component reads an input that is optional or required and which has no new value, an exception is thrown now
• Reworked Cluster component: inputs and outputs are directories, and multiple jobs can be submitted within one iteration

Workflow Engine

• Added new data type "Directory"
• Reworked the way how values/data are sent from one workflow component to another to improve performance and adapt to the new multi-network feature (see below)
• Marked workflow components as deprecated if they are intended to be removed in future versions
• When workflow components (without result views) are finished, the hosting RCE node can now be shut down without breaking the workflow
• Fixed a memory leak that occurred during workflow component execution

Communication Layer

• RCE nodes can now connect to multiple networks without creating a connection between them; previously, this caused all networks to merge into a single, larger network. The new behaviour gives network administrators better control of computing resources.
• Made network connections restartable (usable from Network View and command shell)
• Provided infrastructure for more efficient distribution of node information (for example, the list of published components)
• Improved handling of routing information
• Improved routing performance by reducing the number of re-calculations
• Fixed a server-side resource leak in the ActiveMQ network transport
• Added first draft of an SSH administration console

Others

• Removed unnecessary files in installation folder of RCE (launcher(.exe), eclipsec.exe)
• Improved log messages (e.g. removed irrelevant stack traces, reviewed and reduced warnings)
• "rce.log" is now located in the main directory (previously in "configuration")
• Improved internal event handling
• Shortened path length of temporary files
• General tweaks, bugfixes and performance improvements
